Good project, no spark might just be a combination of dirty points and a poor coil lead. To get at the points you will need to remove the cowl/fuel tank and then the flywheel. Use a puller on the flywheel, there are 3 threaded holes to take the puller bolts. I think the bolts needed are 1/4" whitworth.
Oh and to get the starter pulley off you need a block of wood and a hammer, knock the pulley backwards by putting the wood against the rope slot and give it a good hit to jar it loose.
Have fun
